Is it possible to pickup another line when you are already talking?
I would assume this:
You talk with someone, you put the line on hold, and pickup another line, make a small talk and close the line and resume the original line.
The softkey template does not have the pickup button for an on-hold situation.
Might this be implemented in the future?
I just tested this our lab and found that this can work :) Put the first call on Hold > Select "New Call" Softkey > Pickup > Call is properly redirected to you via Pickup.
Hope this helps!
